I always have to check what sesquicentennial means when I see it describing a stamp even if I can work it out from dates on the stamp itself.

| USA - 21 January 1938 Old Courthouse, Williamsburg VA |
The Pan Am building in Washington DC appeared on an airmail stamp issued in 1947.

| USA - 30 August 1947 |
The plane is one I have never heard of (Martin 2-0-2), but then it was a long time before I flew with Pan Am. I'm also unlikely to make it to Washington now either.
